Design a Custom BoardAbout This Component
Combined digital humidity, pressure, and temperature sensor in 2.5x2.5mm LGA package. Operates from 1.71-3.6V with I²C and SPI interfaces, consuming 3.6µA typical at 1Hz sampling. Specifications include ±3% humidity accuracy, 0.2Pa pressure noise, and -40 to +85°C operating range. Ideal for HVAC control, indoor/outdoor navigation, weather monitoring, and IoT applications.
Package: Bosch (2.5×2.5mm) · 8 pins
Why does this need a breakout?
This tiny 0.65mm pitch LGA-8 package is extremely difficult to hand-solder due to its miniature footprint and hidden pads underneath. A breakout board brings the sensor pins to standard 0.1" headers or breadboard-friendly spacing, eliminating reflow soldering and enabling rapid prototyping of environmental sensing applications like weather stations or HVAC controls.
